I want to go full screen and keep the rendering resolution low to save the performance. Is there a way to scale the size of view3D while keeping the resolution fixed? I tried View3D’s scaleX and scaleY properties but they don’t seem to work. It’s was possible in older versions of Away3D. 
I’d appreciate any help.

Just test reply, because I can’t add topic

Nice idea,, but it wouldn’t save you anything with Stage3D. The number of vertices and the texture sizes are what count most for performance, and they would be the same. If you’re having performance issues, you might want to optimize somewhere else…

Good Luck!

yeah but if you have a slow graphic card screen resolution is important, nearly all PC games have the option to change the rendering resolution.
